Invalid certificate error

I just installed current-20011126 and made a self-signed
certificate as outlined in docs/encryption.txt.

In that document it is stated about 2.7 clients that
"I _think_ for them we'll need a true CA cert and signed cert."

I'm running Red Hat 7.2 with up2date-2.7.2-7.x.6 and
get an invalid client certificate error when I run
up2date aimed at my machine.

I have tried both the self-signed cert alone, and 
catting it together with the Red Hat cert as 
mentioned in encryption.txt, and both get this
error. 

Has anyone gotten around this, or is it that case that
a real certificate is in fact required?  If so, I'll look at
downgrading to a 2.5 client and see how that goes.

Typical output:
